纯净效应准则是用于选择好的设计的常用准则之一.文章致力于建立一个分辨度为IV的2^n-(n-k)设计的纯净两因子交互作用最大数的上界.比较说明对于k=5,6,7,8,9,该上界表现的都比较好.
Clear effects criterion is one of the most often used criteria for selecting good designs. This paper is devoted to build an upper bound on the maximum number of clear two-factor interactions in 2^n-(n-k) designs with resolution Ⅳ. Comparisons show that the upper bound behaves well for k = 5,6,7,8,9.
